Specification of Letters Patent.

METAL-COVERED HOSE.

Application led November 1918. Serial No. m'. y

tion is to provide a 'metal covered hosewhich shall be flexible and capable of short turns or bends'and incapable of being kinked and in which the shape and arrangement of the wires of the metal cover not only impart strength and flexibility but also avoid cutting or abrasion of the tube or hose proper.-

The invention will be claimed at the end hereof but will be first described in connection with the accompanying drawing which is a view, `partly in section and partly in elevation, of a' hose embodying features of.

the invention.

In the drawings 1, is a tube as of duck and rubber which may be an ordinary hose. 2 and 3, are a pair of half round rods or wires disposed one 3, with its fiat face and theother 2, with its round face toward the surface of the tube 1. Each wire or rod is arranged around the tube in the form of a. spiral having a pitch substantially equal to the width of the flat face of the other wire. The pitch of each spiral is substantially the saine and the space formed bythe pitch bel tween the adjacent coils is shown at 4, and

this space et," corresponds substantially in width with the width of the flat face of the rods or wires so that the space 4, between the adjacent coils of one spiral receives the coils of the other spiral.

The described half round form of the rods or wires prevents cutting or abrasion of the surface of the tube and also in connection with the spacing of the coils imparts fiexibility to the article as a whole. Moreover, each wire or rod may contact with the face of the -tube l, so that strength and lightness are added to the above named advantages.

l/Vhat I claim is;

A inetal covered hose tube .comprising the combination of a tube and a pair of substantially half round wires disposed one with its Hat face and the other with its round face toward the surface of the hose tube said round and fiat faces bein flush and each in contact with the hose tu e and each arranged around the tube in the form of a spiral having a pitch substantially equal to the width of thel flat face of the other, substantially as described.

In testimony' whereof I have hereunto signed my name.

HOWARD W. GOODALL.
